Researchers trained a quadruped robot to cross a balance beam
A team of Italian robotics researchers created a quadruped robot that can balance on two feet.
HyTAQ hybrid quadrotor robot travels by air and land, leaves us no place to hide (video)
Few robots can travel gracefully through more than one medium; more often than not, they're either strictly airborne or tied to the ground. The Illinois Institute of Technology's HyTAQ quadrotor doesn't abide by these arbitrary limits. The hybrid machine, designed by Arash Kalantari and Matthew Spenko, uses the same actuators to drive both its flight as well as a surrounding cage for rolling along on the ground, quickly switching between the two methods. It's clearly adaptable, but using the one system also provides large power advantages over a traditional quadrotor, Spenko tells us. While HyTAQ's battery lasts only for 5 minutes and 1,969 feet of pure flight, that jumps to 27 minutes and 7,874 feet when the robot can use a smooth floor instead -- and of course, it can hop over ground obstacles altogether instead of making a detour. The range of the robot and its pilot are the main limiting factors, but the patent process is already underway with hopes of winning commercial deals. We're both excited and worried as a result; as wonderfully flexible as HyTAQ is, widescale adoption could lead to especially relentless robots during the inevitable takeover.
HyQ is the latest all-terrain quadruped bot, tells Big Dog to bring it on (video)
You might not know this, but you can literally never have enough all-terrain quadrupedal robots... at least according to us (John Connor might disagree). So, while HyQ from the Italian Institute of Technology might bear more than a passing resemblance to Boston Dynamic's Big Dog, we won't hold it against the creators. The Hydraulic Quadruped robot (HyQ for short) was first dreamed up in 2008, but the project is only now coming into its own. Researchers at IIT took the bot for a stroll outside of the confines of a laboratory and treadmill for the first time. They've also stepped up the treadmill testing by bumping up the incline and practically throwing obstacles at it. Impressively, HyQ holds his own, even as his creators pelt it with shipping pallets. Check out the video after the break to see the cybernetic crawler in action.
Aakash put on notice as BSNL and Pantel pair up to produce T-Pad
The last thing that the Aakash project needed was a more handsome, similarly priced commercial rival swooping in and stealing all of its thunder. Sadly that's what's happened: Bharat Sanchar Nigam Limited (BSNL), itself currently under investigation for corruption allegations, has announced a similarly low priced tablet in partnership with Pantel International. The T-Pad IS701R costs Rs 3,250 ($66) compared to the Aakash's Rs 2,999 ($60) but this device has a faster 1GHz processor and runs Gingerbread on a 7-inch 800 x 600 resistive display. However it's not all sunshine and roses, unlike the Government-sponsored slate, there is no GPRS modem in this edition. If you want freedom from WiFi, it'll cost you Rs 10,999 (or $223). So how do the two tablets stack up? Head on past the break and we'll show you in a little more detail. [Thanks, Syed]
Aakash lurches toward another crisis as India loses patience with DataWind
The conflicts and behind-the-scenes drama surrounding India's Aakash project once again threaten its existence. Despite a record-breaking 1.4 million pre-orders gained in under a fortnight, maker DataWind has only shipped 10,000 units to nearly universal derision. Early adopters have found the processor too slow, battery life too short and the resistive touchscreen difficult to use. Kapil Sibal's Human Resource Development ministry now plans to re-open tendering for a replacement contractor and withdraw DataWind's deal for a further 90,000 units. An anonymous ministry official has said that they've seen "sufficient interest [...] to get better specifications at the same or lower price."In response, DataWind has claimed that its development-partner, the Indian Institute of Technology, pulled a bait-and-switch, demanding at the eleventh hour that the tablet meet US military criteria for durability -- including being able to withstand four inches per hour of "sustained rain." Work has been on hold since then but neither party can afford another delay. DataWind promised it would sell the commercial version of the slate this month, while Kapil Sibal has promised that a second edition of the Aakash would be announced in April.
Robot arm learns to flip pancakes, can never know the joys of tasting one
We'd like to pretend to be all serious about the science behind teaching a robot arm to teach itself a complicated motion like pancake flipping. We'd drone on and on about how the combination of demonstrated motion, trial-and-error, and object motion tracking come together for some "Expectation-Maximization based Reinforcement Learning," but really we just can't stop giggling at all the pancake misses perpetrated by the robot on video, which can be found after the break.
Ilinois Institute of Technology jumps on the iPad bandwagon
Along with Seton Hill and George Fox University, The Illinois Institute of Technology in Chicago will be giving a "free" iPad to between 500 and 600 incoming freshman. Since I'm sure they will be giving out the base model, this will cost the school between $250,000 and $300,000. In comments on the previous posts, it was clearly brought out that there's no such thing as a free lunch, and this may be nothing more than a clever marketing gimmick to increase enrollment in these financially strapped times. With IIT tuition coming in at a high, but in the ballpark, $31,363, I can easily understand that a school will try any number of things to keep the enrollment applications rolling in. In this case there may more to it than marketing, since IIT already teaches courses in mobile application development and there is an expectation of faculty in computer science and engineering to build specific iPad apps for use in their courses. With three schools on this particular bandwagon and more to come, where do you stand on this? Is this a marketing gimmick or an honest interest in implementing a new and useful educational technology? [via chicagobreakingnews.com]
